An apparatus for treating food substances includes a cutting plate defining a longitudinal axis and having at least one cutting surface for supporting food substances and a collecting tray releasably mountable to the cutting plate. The collecting tray defines a reservoir for collecting food substances cut on the culling surface. The collecting tray may define a spout adapted to facilitate pouring of liquid material of the food substances. The collecting tray may define first and second spout segments. The first and second spouts may be disposed in diametrical opposed relation.

A force balanced irregular pitch reamer is provided that is particularly well suited for precision operations requiring small tolerances. More specifically, a reamer is provided having a shank, a body portion, and a plurality of cutting teeth extending outwardly therefrom. The teeth are spaced at non-uniform intervals around the body portion, wherein each tooth includes a cutting surface and rake face, and defines a rake angle between the rake face and an imaginary line extending from the central or longitudinal axis of the reamer to the cutting surface. In operation, the reamer is rotated about its central axis and is plunged into a formed hole sized slightly smaller than the reamer such that the reamer engages the workpiece and produces a smooth finished hole. Each tooth generates a cutting force with determinable magnitude and direction to define cutting force vectors. Advantageously, the reamer of the present invention includes teeth having rake angles cooperatively formed such that the cutting force vectors are substantially offset by one another, thus balancing the reamer and providing a finished hole that is substantially free from any lobes and is properly sized.

A railroad trackwork frog assembly is provided with a pair of wing rail components, with a centrally positioned body component comprising an integrally formed V-shaped point element having a pair of gauge lines, an integrally formed pair of wing elements having a pair of guard lines, and integrally formed flangeways separating said point element from said pair of wing elements, and with fasteners joining the body component wing elements to the wing rail components in a manner whereby the point element gauge lines are truly parallel to the wing element guard lines and are uniformly separated from said wing element guard lines uniformly by a distance of approximately 13/4-inches.

A right angle, modular machining head can be removably mounted on the too head of a CNC machining center to provide contour machining of a work piece around a C-axis. The modular head includes a rotating drive that moves the tool around a contour axis, producing nutational motion allowing close contouring of a work piece. The tool can be powered by a driven spindle on the tool head, or by a motor carried within the modular head. A locating connection between the modular head and the tool head, in combination with a position signals produced by a rotary encoder on the modular head registers the exact position of the tool within the coordinate reference system used by the machining center control system.

The present invention comprises methods of machining a workpiece. In one embodiment, a method includes positioning a workpiece in a first position in a process station of a machine system, and forming at least one check feature on the workpiece. A position of the check feature is then sensed while the workpiece is positioned in the first position, and one or more machined features are formed on the workpiece relative to the check feature while the workpiece is positioned in the first position. The workpiece is then moved from the first position to a second position within the process station, and a position of the check feature is again sensed while the workpiece is positioned in the second position. One or more machined features are then formed on the workpiece relative to the check feature while the workpiece is positioned in the second position.

Reinforced structural assemblies and methods for forming such assemblies are disclosed. In one embodiment, a reinforced structural assembly includes an engagement portion having at least one projecting structure extending outwardly from the engaging structure, and a receiving portion having at least one recessed structure that slidably receives and fixably retains the projecting structure. In another embodiment, a method for constructing a reinforced structural assembly includes positioning at least one projecting structure on a first substrate, positioning at least one recessed structure on a second substrate. The at least one projecting structure and the at least one recessed structure are slidably coupled and fixably secured.

A precision shear is provided which allows the removal of material from a machined part. The shear provides a precision cut that requires little or no finish grinding or polishing thereby reducing the time required to produce a machined part. The precision shear may be operated by hand or attached to a machine.

An apparatus for treating food substances, includes a cutting plate defining a longitudinal axis and having at least one cutting surface for supporting food substances and a collecting tray mounted with respect to the cutting plate. The collecting tray is dimensioned and adapted to transition between a first stored condition to facilitate storage or transport thereof and a second operative condition to provide a reservoir for collecting food substances cut on the cutting surface.
